OK, please let me know if you see anything incompatible. I plan to use the Zinsser 2# sanding sealer over teh entire guitar, then Z-poxy the back side and neck to pore fill, then use about 8-10 coats of Tru-oil as my finish on the entire guitar. I've never used Z-poxy before and have always just used the Tru-oil to fill pores in the past. I have rifle stock over 20 years old that were done with Tru-oil and no problems yet. Is there an edvatntage using the Z for filling over just additional coats of T-oil? |

I lay down the zpoxy over bare sanded wood. Sand and repeat until the surface is pore free. I shellac over that. The key is that zpoxy does not adhere as well to shellac. However, after prepping the ZP'd surface, shellac adheres quite well. I can't comment on True Oil. |

I'm not sure that there are any "advantages" as such. I have used Tru-oil on my guitars but not over Z-poxy. I like the look of the Z-poxy - sometimes I'm tempted to leave it as a finish in it's own right on the back/sides. It has a nice look/feel and I suspect is pretty tough. Up to now I've lacquered over it. People fp over it so I would think that Tru-oil will go on fine - but it would be worth trying out on some scraps first to check the look, adhesion and curing of the Tru-oil. I don't think you will need and sanding sealer though - Z-poxy on the prepared wood I suspect would be best. Others have reported problems of Z-poxy adhering to shellac. Z-poxy I suspect is easier to apply than the Tru-oil rubbed/sanded into the pores. I suspect it will come down to the looks in the end. |

I'm assuming NO Z-poxy on teh soundboard though--correct? Just sealer and Tru-oil |

I've used Tru-Oil over shellac with no problems. In fact for the top I'd probably just seal with shellac and then apply Tru-Oil. |

I've used Tru Oil over Zpoxy on 5 mahogany necks with good results. ~8 coats total lightly buffed with 0000 steel wool between the last 2-3 coats. I haven't tried using it on any dark toned wood. I wish my lacquer finishes were as easy and consistent. BobK |

You are correct, no ZPoxy on the Top, only use the Shellac to seal. TruOil will go over both really well with no problems. Mike |

My first three have been tru oil over shellac sealer. I like it. I also put tru oil on my first fret board, but took it back off as it gave it a plastic look (ebony FB). On my next two I used the LMI FB oil and I really like it as a finish on the FB. Ron |

I just tried TruOil on an African mahogany neck. I filled the pores with the System3 epoxy, sanded back to the wood surface after each coat. The TruOil went on with no problems. Looks real nice, too. I plan to finish it up with wax and 0000 steel wool, but I set the neck aside for a couple of weeks to make sure the TruOil had dried good and hard. |

Terry, if the neck wood has pores that is the way that I do it, sand back down leaving the ZPoxy in the pores. Then I put a coat of the Sanding sealer. I use the Sanding sealer (same maker) only if I am finishing Maple or Cherry, not pourous and Zinser Seal Coat (shellac) 2 coats if I do the top with TruOil. On the Back & Sides, I sand back but then also put a light diluted cover coat back on to pop the grain and seal then TruOil over that. I have found that TruOil and recently Danish Oil finishes are both easy and work on and over just about everything. Especially the TruOil, it gives a really nice shine that is really smooth. I TruOil all my necks no matter what finish I am using on the body and headplate. Like the feel Mike |

Terry, I've had good results doing the following. I apply the first coat of Zpoxy with my finger and lightly sand when dry. Second coat also applied with my finger but immediately wiped down with a dry clean cloth. Follow up with a light sanding mainly to look for imperfections and repeat if necessary. So, yes, I leave a thin film on mine. Then on to the Tru Oil. BobK |

I haven't used any filler on my mahogany necks. I sand through 800, apply the first two coats of tru-oil with 0000 steel wool, then apply the rest, using the steel wool between coats, veerrrry lightly. Ron |
